48/2-224 - Madrone (SLAC)

The Coherent CAPTAIN-Mills (CCM) experiment is a 10 ton liquid argon scintillation and Cherenkov detector at the Los Alamos Neutron Science Center. The detector is located 90deg off-axis and 23m away from the Lujan Facility's stopped pion source which will receive 2.25 10^22 POT in the ongoing 3 year run cycle. The short duration 290ns proton pulse and delayed arrival time of spallation neutrons allows CCM to probe rare processes with very low backgrounds. The high-rate of pion production and intense flux of other particles at the Lujan source allow CCM to probe a wide variety of dark sector models, including possible explanations to the short-baseline neutrino anomalies and MeV-scale Axion-Like-Particles. In this talk I present a portion of CCM’s dark sector search program in the context of the short-baseline neutrino anomalies and other outstanding problems in the field. I also discuss a new experimental effort at the Lujan facility that leverages low-energy nuclear recoils from coherent scattering in a doped Cesium Iodide detector.
